bit 7
Unimplemented: Read as '0'
ABTF: Message Aborted Flag
1 = Message was aborted
0 = Message completed transmission successfully
MLOA: Message Lost Arbitration
1 = Message lost arbitration while being sent
0 = Message did not lose arbitration while being sent
TXERR: Transmission Error Detected
1 = A bus error occurred while the message was being transmitted
0 = No bus error occurred while the message was being transmitted
TXREQ: Message Transmit Request
1 = Buffer is currently pending transmission
0 = Buffer is not currently pending transmission
Unimplemented: Read as '0'
